  Analogues of xanthones——Chalcones and bis-chalcones as α-glucosidase inhibitors and anti-diabetes candidates

  摘要：

  Two series of compounds (chalcones and bis-chalcones) were designed, synthesized, and evaluated as aglucosidase inhibitors (AGIs) with 1-deoxynojirimycin as positive control in vitro. Most of the compounds with two or four hydroxyl groups showed better inhibitory activities than 1-deoxynojirimycin towards aglucosidase with noncompetitive mechanism. Moreover, most of the hydroxy bis-chalcones exhibit good a-glucosidase inhibitory activities in enzyme test. Inspiringly, bis-chalcones 2g (at 1 mu M concentration) has stronger effect than 1-deoxynojirimycin on reducing the glucose level in HepG-2 cells (human liver cancer cell line).
